I got confused by this too, but it turns out that the LinearAlgebra`
context contains some built-in symbol (not the ones in the old
LinearAlgebra` collection of packages):

In[4]:= Names["LinearAlgebra`*"]

Out[4]= {"LinearAlgebra`Arnoldi", \
"LinearAlgebra`MatrixCayleyTransform", \
"LinearAlgebra`MatrixConditionNumber", "LinearAlgebra`MatrixPhi", \
"LinearAlgebra`MatrixPolynomial", \
"LinearAlgebra`RealSymmetricMatrixQ", \
"LinearAlgebra`SymmetricMatrixQ", \
"LinearAlgebra`UpperTriangularizeMatrix", \
"LinearAlgebra`VandermondeInverse", \
"LinearAlgebra`VandermondeMatrix", \
"LinearAlgebra`VandermondeResidual", "LinearAlgebra`VandermondeSolve"}
